"For two decades, X has been the foundation for Linux graphics. Ubuntu's decision late in 2010 to switch to Wayland shakes things up all the way to those roots. Just over a month ago, the official 1.0.0 release of Wayland appeared, as well as its associated Weston project. How will these milestones affect working GUI programmers? What will happen to all the existing toolkits - Qt, wxWindows, Tk, and others - on which so many graphical applications already depend?"

GPU glyphs are the final piece needed to allow apps to draw resolution independently. Currently apps are forced to query the display resolution and do all kinds of calculations involving anti-aliasing. All of that platform specific code would disappear.

HTML is an example of something that is partially resolution independent.

Uh, you don't need hardware acceleration for resolution independence, you just need the WM and all the toolkits designed for it. Currently they aren't designed top-down for that and GPU-generated glyphs won't magically fix them.
